Add a submodule (gitlink) and move it to a different spot:
|
|
$ cd ..
|
|
$ git init -q gitsubmodule
|
|
$ cd gitsubmodule
|
|
$ touch subalpha
|
|
$ git add subalpha
|

|
|
$ cd ../gitrepo
|
|
|
|
$ git submodule add ../gitsubmodule
|
|
Cloning into '$TESTTMP/gitrepo/gitsubmodule'...
|
|
done.
|
|
$ fn_git_commit -m 'add submodule'
|
|
$ sed -e 's/path = gitsubmodule/path = gitsubmodule2/' .gitmodules > .gitmodules-new
|
|
$ mv .gitmodules-new .gitmodules
|
|
$ mv gitsubmodule gitsubmodule2
|
|
|
|
Previous versions of git did not produce any output but 2.14 changed the output
|
|
to warn the user about submodules
|
|
|
|
$ git add .gitmodules gitsubmodule2 2>/dev/null
|
|
$ git rm --cached gitsubmodule
|
|
rm 'gitsubmodule'
|
|
$ fn_git_commit -m 'move submodule'
|
|
|
|
Rename a file elsewhere and replace it with a symlink:
|
|
|
|
$ git mv beta beta-new
|
|
$ ln -s beta-new beta
|
|
$ git add beta
|
|
$ fn_git_commit -m 'beta renamed'
|
|
|
|
Rename the file back:
|
|
|
|
$ git rm beta
|
|
rm 'beta'
|
|
$ git mv beta-new beta
|
|
$ fn_git_commit -m 'beta renamed back'
|
|
|
|
Rename a file elsewhere and replace it with a submodule:
|
|
|
|
$ git mv gamma gamma-new
|
|
$ git submodule add ../gitsubmodule gamma 2>&1
|
|
Cloning into '$TESTTMP/gitrepo/gamma'...
|
|
done.
|
|
$ fn_git_commit -m 'rename and add submodule'
|
|
|
|
Remove the submodule and rename the file back:
|
|
|
|
$ grep 'submodule "gitsubmodule"' -A2 .gitmodules > .gitmodules-new
|
|
$ mv .gitmodules-new .gitmodules
|
|
$ git add .gitmodules
|
|
$ git rm --cached gamma
|

rm 'gamma'
|

$ rm -rf gamma

|

|
|
